Time to be picky about shell-specific stuff. :-)

Actually, "set" is a csh-ism. In bash, it's just "VARIABLE=VALUE".
"set" does print out all the variables, though, as well as all defined
shell functions. I think "env" only prints exported variables, as does
"export", although in a very different format, sticking "declare -x" in
front of everything.
In csh, 'export' is replaced by 'setenv', as in "setenv VARIABLE VALUE".
Note that there is no '='.
All this and more is yours to discover in the wonderful world of
"man bash" and "man csh". :-)

If you're running csh or tcsh, you would say
set path=($path .)
Yours nit-pickerly,
